Na^+11) 1_(11)Na2overline (e),8overline (e),1overline (e).

It looks like you're presenting the electron configuration of a sodium ion (Na⁺). Let's break it down:1. **Neutral Sodium Atom (Na):** - Atomic number: 11 - Electron configuration: 2. **Sodium Ion (Na⁺):** - Sodium loses one electron to achieve a stable electron configuration similar to neon (Ne). - Electron configuration of Na⁺: So, the electron configuration of the sodium ion (Na⁺) is: This configuration shows that the sodium ion has lost its one valence electron, resulting in a stable noble gas configuration.
